Neon Setup Recommendations
The NRT/NRM should be registered as part of a scheme before being installed in the field.
This will allow for commissioning of the NRT/NRM and verification that communications
can be established between the NRT/NRM and the Neon server.
Once in the field the NRT/NRM should be placed in the area of greatest signal strength. A
good test for this is to use a mobile phone using the same carrier as the NRT/NRM, as the
signal strength indicator will show the best location.
Note that due to the slow refresh rate of the mobile phone signal strength indicator, it is
necessary to hold the mobile phone in place for between 30 to 60 seconds to obtain an
accurate reading. If a mobile phone on the same carrier network is not available it is
possible to use the NRT/NRM itself to determine signal strength. .
Avoid installing the NRT/NRM enclosure in direct sunlight, as cool operating temperatures
will aid longevity of the internal components.
Avoid placing the NRT/NRM enclosure inside a metal box, or in an area with large
amounts of metal around the NRT/NRM enclosure, as this can adversely affect the
communication abilities of the NRT/NRM. If the NRT/NRM must be located within a metal
enclosure, an external antenna will be required.
Install the NRT/NRM enclosure in a secure location to avoid tampering and vandalism.
Position the enclosure to ensure cables from NRT/NRM to field device(s) are as short as
practical.
If the NRT/NRM is to be used for real-time communication, or for a higher than usual
download schedule (refer to Table 1), an external power supply may be required to avoid
frequent battery replacement. Provision for this should be considered during the
installation, such as installing the NRT/NRM within range of a mains power outlet.

NRT/NRM Connections
As there are many models of NRT/NRM, the wiring connections are listed in the
Appendices of this manual by product number.

Field Installation of an NRT in a Weatherproof Enclosure
Determine the location for the NRT based on site requirements as well as the installation
recommendations stated on the previous pages.
Loosen the four plastic cover screws at the front of the weatherproof enclosure and
remove the cover.
For the purpose of this section, it is assumed that the NRT is operational as described in
Installation Recommendations.
Fit the aluminium NRT mounting plate onto the base of the weatherproof enclosure,
aligning horizontally so that the four threaded inserts are uppermost and to the right-hand
side. Align the drilled mounting holes in the plate with four fixing points, to position the
NRT in the upper part of the enclosure once mounted. Secure using the four short thread-
cutting screws, taking care not to over-tighten.
